Five, embodiment
Consult Fig. 3, Fig. 4, shown in Figure 5, the preferred embodiment of the utility model thin type charger comprises: a charger body 30, its bottom surface are provided with a plug 40, in order to be connected a socket (not shown), to obtain AC power (AC).This plug 40 is set as the form that can fold at charger body 30 bottom surface chases 37.Aforementioned charger body 30 can be made up of lower house 31,32 on, is provided with a spatial accommodation 33 in the middle of it.
Again, two charging slot 50L, 50R that supply secondary cell B to insert are to be provided in this charger body 30 left and right sides.Moreover for conveniently putting or take secondary cell B, charging slot 50L, 50R bottom surface are provided with a concave arc 36, but are not limited to this.
One charging control circuit plate 60 is located at the spatial accommodation 33 in the middle of the charger body 30, at least comprise on this circuit board that an AC changes DC change-over circuit 61, convert DC power supply DC in order to AC power AC, for charging slot 50L, the 50R required power supply that charges with plug 40 input.
The claimed technology contents of charging non-the utility model of control loop is so repeat no more.
Maximum of the present utility model is characterised in that, the design of these left and right two charging slot 50L, 50R, also promptly these two charging slots be forgo existing (Prior Art) be located at charging with the structure on the electronic building brick 12, but it is located at charging control circuit plate 60 both sides, and opening is towards left and right, like this, the thickness of whole charger body 30 be can reduce, its thin typeization and light and handyization made; And left and right charging slot 50L, 50R are designed to and can insert charging for 3/AA or the wherein arbitrary type secondary cell of 4/AAA under the restriction of thin typeization.For reaching this purpose, the technological means that it adopted at first is to connect protruding dew top 41 that two electroconductive elastic sheets 71 and plug 40 extend charger body 30 inside at front end to be electrical and to contact, so that power supply is transported to charging control circuit plate 60; Further electrically connect two first electrodes 72, and make first electrode contact surface 721 expose breach 34 respectively, can electrically connect after inserting for battery at and arranged on left and right sides charging slot 50L, 50R tail end at charging control circuit plate 60 tail ends.Moreover, one has second electrode (73) of flexible conducting function, be located at the corresponding end of first electrode 72, thereby be fastened in the draw-in groove 35 in the charger body 30, it is to be electrically connected at charging control circuit plate 60, and as Fig. 6, shown in Figure 7, it includes: an outer sleeve body 731, front and back ends is opening-like, and the rear end possesses the stop surface 732 that contracts in; Body 733 in one is that front end is the opening ducted body, can be inserted in outer sleeve body 731, and the relative stop surface 732 of front end face is provided with an outside flange surface 734, and makes the protruding front end that is exposed at this charging slot 50L, 50R of end face thereafter; One spring 735 is put at interior body 733; One lid 736 is fixed on outer sleeve body 731 front end faces.
So second electrode 73 of the present utility model has Telescopic, the long guiding element 74 that its front end face and is connected charging control circuit plate 60 contacts and conducting, and described long guiding element 74 can be a metal clips, or element such as electric wire all can.Thereafter end face protrudes out the front position at left and right charging slot 50L, 50R, as shown in Figure 8, the secondary cell B1 that the charging slot of this moment just can be inserted the 4/AAA model, No. 4 electricity ground that promptly are commonly called as, and second electrode 73 is by body 733 in contained spring 735 ejections, make thereafter that end face contacts with secondary cell B1 negative pole (-), and force contact-making surface 721 conductings of positive pole (+) Yu first electrode 72 of secondary cell B1, form charge circuit smoothly.It is to be noted, the utility model one preferred embodiment is that the contact-making surface 721 with first electrode 72 is arranged with in the breach 34 of this left and right charging slot 50L, 50R tail end, also be that contact-making surface 721 only embeds and the conducting connection at the protuberance of battery B1 positive pole (+), when inserting as this reverse battery, its negative pole (-) is a planar base surface, can't stretch into this breach 34, therefore can not form the charge circuit of conducting, design can be avoided reverse charging thus, guarantees safety and useful life.
Consult shown in Figure 9, secondary cell B2 for the 3/AA model, No. 3 batteries that promptly are commonly called as, because No. 3 batteries are big than No. 4 batteries, so, contract in the interior body 733 of second electrode 73 of this moment, but still the rear end face of body 733 leans negative pole (-) at secondary cell B2 in making, with form the utility model can be simultaneously for the secondary cell charge of 3/AA or two kinds of different models of 4/AAA.
Consult Fig. 7, Fig. 8, shown in Figure 9, second electrode 73 of the present utility model, no matter it is as shown in Figure 8, body 733 protrudes out in being, or shown in Figure 9, the state that contracts in the body 733 in being, it remains the excellent electrical property contact, promptly should in body 733 protrude out or in when contracting, its flange surface 734 contacts conducting with the internal face of outer sleeve body 731 all the time, also promptly with lid 736 conductings; In addition, this interior body 733 also keeps conducting states with lid 736 all the time by the spring 735 of inside; Like this,, can prevent the loose contact when second electrode 73 is flexible in dual conducting state, so, second electrode 73 of the present utility model no matter protrude out or in arbitrary state that contracts, all can keep excellent electrical property to contact, guarantee the reliability of charging.
The utility model is by above-mentioned technological means, charging slot is located at charging control circuit plate both sides, and opening fully uses the space towards both sides, make the charger volume be flat thin typeization, its product thickness is no more than 2cm, width is 5.2cm, and length is 7cm, so, also littler and thin than a cigarette package volume, have conveniently and carry, be connected charging nearby with socket, and can supply the effect of the secondary cell charge of two kinds of different models according to demand.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
